colletotrichum species are associated with citrus plants as pathogens, saprobes and endophytes. according to the most recent multigene phylogenetic analysis, a lot of changes were happened in the taxonomy and species delimitation in the genus colletotrichum. in this investigation, 292 colletotrichum isolates were obtained from leaves, fruits and stems of citrus species at golestan, mazandaran, ...

the study of karst phenomena and its potentials has had always a particular importance in semi-arid zones of iran, specifically due to the lack of water sources. in this paper, we are going to discuss the landscape morphology in karstic areas, and the way we can have an ecological planning approach to it. maharlu karst basin was selected as the case study of karstic area, and kaftarak mount in ...

fifteen yarrow populations from different species achillea millefolium l., a. biebersteinii l. and a. nobilis, from different geographical areas of iran were studied using 24 morphological traits and peroxidase profiles. comparison of mean values of different phenotypic traits show a. millefolium and a. biebersteinii l. had higher plant height and crown diameter; however, a. nobilis had higher ...

magnetite (fe 3 o 4  and nio) nanoparticles with a size range of 40–60 nm were prepared by sol-gel technique in nano and micro reverse micelles (water- in-oil). the surface properties, size, morphology and crystallographic structure of fe 3 o 4 and nio particles are characterized by means of x-ray diffraction, transmission electron microscope and scanning electron microscope which will give muc...

background : haemonchosis has a negative effect on the farming industry throughout the world, especially in the tropic and sub-tropic countries. the present study was carried out to differentiate haemonchus species from its main hosts in iran, including sheep, goat and camel.   methods: the identification took place based on the morphometrics of the spic-ules and molecular characters. two hundr...

in this study ten pairs of superior gland of third eyelid of 10 adult male camels free of apparent ocular disease were examined to compare the normal anatomical and histological properties of these glands. after dissecting, all of the glands were characterized and measured (length and width) on both the left and right side. in the camels, the superior gland of the third eyelid was oval shaped a...

the present study evaluated effects of 0.0%, 0.5%, 0.75% and 1.0% l-threonine in diet on performance and gastrointestinal tract development in broiler chickens during summer. from 0 to 42 days old, body weight gain was greater in 0.75% l-threonine fed birds than in 0.0% and 0.5% l-threonine fed birds (p0.05). during the growth period, 0.75% l-threonine fed birds had the highest body weight gain...

pollen morphology of some species of the genus malus (rosaceae) was investigatedtaxonomically. all species are characteristic by tricolpate pollens. exine sculpturing is variable but is mostlystriate. however, species may differ in degree of density of ridges and their orientation. the exine patterns inm. trilobata and m. florentina are very similar and were characterized by short and very bran...

patients and methods twenty-two young men (age = 23.34 ± 2.56 years, weight = 72.47 ± 12.01 kg, and height = 174.10 ± 5.75 cm) were recruited and randomly assigned into control (n = 10) and hiit (n = 12) groups. echocardiography was used to evaluate left ventricular mass (lvm), end-systolic volume (esv), end-diastolic volume (edv), interventricular septal wall thickness (ivswt), stroke volume, ...
